摘要：Este trabajo integra satélite-LIDAR para comparar la evaluación de stock de carbono en alta resolución en un bosque de manglar (Rincón Mosquito) en la zona costera del mar Caribe. Se comparó la altura de vegetación resultante de la extracción de un modelo de altura de la vegetación satelital EROS-B y un LIDAR aerotransportado vs datos en campo. Los satélites ofrecen una oportunidad de monitorear cambios en el carbono forestal causados por la deforestación y la degradación, igual que nuevos métodos aéreos, especialmente el método LIDAR, ofrecen una forma de estimar la densidad del carbono forestal, lo cual ayuda en el desarrollo de líneas base para inventarios de carbono. Luego de calcular la biomasa total desde los datos de satélite y LIDAR, se comparó la medida de biomasa tomada en campo. En términos de escalas detalladas se puede concluir que el sensor con mayor precisión es el LIDAR al tener un nivel de resolución espacial que permite gran detalle de la masa arbórea., El uso de estéreo pares satelitales es viable en grandes extensiones y no en pequeñas áreas, donde particularmente en los últimos años, los datos tomados con vehículos aéreos no tripulados parecen ser una alternativa más viable en disponibilidad y costo.↓This work integrates satellite-LIDAR to compare the evaluation of high-resolution carbon stock in a mangrove forest (Rincón Mosquito) in the coastal area of the Caribbean Sea. The height of vegetation resulting from the extraction of a height model of the EROS-B satellite vegetation and an airborne LIDAR vs. field data was compared. Satellites offer an opportunity to monitor changes in forest carbon caused by deforestation and degradation, just as new aerial methods, especially the LIDAR method, offer a way to estimate forest carbon density, which helps in the development of lines base for carbon inventories. After calculating the total biomass from the satellite and LIDAR data, the biomass measurement taken in the field was compared. In terms of small scales it can be concluded that the sensor with greater precision is the LIDAR by having a level of spatial resolution that allows great detail of the tree mass., The use of stereo satellite pairs is viable in large areas and not in small areas , where particularly in recent years, data taken with unmanned aerial vehicles seems to be a more viable alternative in availability and cost.
